 Consists simply of a copper tube and a powerful cylindrical magnet with an outer diameter just a bit smaller than the inner diameter of the tube. There are three copper tubes available in the demo room. Their lengths aren't exactly the same but are close to 50cm.  Consists simply of a copper tube and a powerful cylindrical magnet with an outer diameter just a bit smaller than the inner diameter of the tube.

-A smaller-diameter copper tube with a slit is also available, as well as a pair of aluminum tubes (which work, but not as well because the conductivity of aluminum is lower) and a long solenoid (which seems like it should work, but essentially ​doesn'​t due to the way the induced currents cancel).+A smaller-diameter copper tube with a slit is also available, as well as a pair of aluminum tubes ((which work, but produce a smaller braking force because the conductivity of aluminum is lower)) and a long solenoid.

If you can measure precisely enough, it may be possible to register a (very smalldifference.))
